[mythtv] mythfrontend is always displayed

[Mark Jeske]

I've just gotten everything up an running on a stock redhat 8.0 instance
and have one problem.  When I run mythfrontend I see the interface and
can select items, etc.  However, when I choose 'Watch Tv', the live tv
window doesn't display although it is running because I get sound and
can change channels with the arrow keys.

It's as if the mythfrontend has taken over the display and won't let the
mythtv program show.  I can run mythtv by itself and everything is ok.

Also, I get the following message on the console from my startx which I
think is related:

Window manager warning: Window 0x180004b (mythfronte) sets SM_CLIENT_ID on
itself, instead of on the WM_CLIENT_LEADER window as specified in the ICCCM.

This is use the default gnome window manager in Redhat 8.0

Thanks in advance,
mark

P.S.  Great work to everyone involved!
